There will come a time when you would like to simply transfer a file from one iOS device to another or to a Mac; it's inevitable. When the time arises, you will discover as most of us already have that the process is not as straightforward as one would think, considering how powerful these devices are. The most common methods used up to this point have been emailing oneself, cloud services like iCloud or Dropbox, file sync with the USB cable and iTunes or pleading with the always capricious Camera Connection Kit.
Instashare for iOS is like AirDrop for mobile devices as it quickly and painlessly copies any file from one device to another over WiFi or Bluetooth without a direct connection to the internet.
Instashare for OSX currently in beta, adds the ability to send files to and from your Mac and your iOS devices.
Both versions of Instashare are free; however, the iOS version is ad-supported and the ads can be removed by a $0.99 in-app purchase. Instashare for Android and Windows are currently in development.
